I'm using Redux Toolkit but I can't seem to find a way to add a new value of an array of objects.

Here's my reducer:

import { createSlice, current } from "@reduxjs/toolkit"

const initialState = {
  positions: []
}

export const userSlice = createSlice({
  name: "user",
  initialState,
  reducers: {
    setPositionsAction(state, { payload }) {
      state.positions = payload
    },
    addPositionAction(state, { payload }) {
      state.positions.push(payload)
    }
  }
})

export const {
  setPositionsAction,
  addPositionAction
} = userSlice.actions

export default userSlice.reducer

I'm dispatching the request after a successful axios request

dispatch(addPositionAction(response))

But the state gets deleted and only contains the new value I just added, removing completely all the data that was containing before.

What am I missing?
